New ideal for one . Just whelped a litter on the 5th and used this , has worked real good . Instead of PVC I took a stiff piece of rubber hose 1 1/4" OD wrapped around the inner floor where sides meet flooring , shot wood screws ever 12" apart into floor . Curve it around the corners and ur done . So far it's worked great . Just another ideal that will keep pups from being mashed in the corners and cheep to boot .
